The wavelength of light of a particular colour is 5800 Å.
Express it in nanometre.
In the vernier callipers, there are 10 divisions on the vernier scale and 1 cm on the main scale is divided into 10 parts. While measuring the length, the zero of the vernier lies just ahead of the 1.8 cm mark and the 4th division of vernier coincides with a main scale division.
(a) Find the length.
(b) If zero error of vernier callipers is -0.02 cm,
What is the correct length ?
While measuring the length of a rod with a vernier callipers, below shows the position of its scales. What is the length of the rod?
Fig., below shows the reading obtained while measuring the diameter of a wire with a screw gauge. The screw advances by 1 division on the main scale when circular head is rotated once.
Find:
(i) Pitch of the screw gauge,
(ii) Least count of the screw gauge and
(iii) The diameter of the wire.
Why is the metre length in terms of the wavelength of light considered more accurate?
Define the term least count as applied to a vernier callipers.
Figure shows a screw gauge in which circular scale has 100 divisions. Calculate the least count and the diameter of a wire.
What is the least count in the case of the following instrument?
Metre scale
What is the least count in the case of the following instrument?
Screw gauge
